What is gravity?

• The force that makes things spin

• The force that makes things float in space

• The force that pushes everything away from the ground

• The force that pulls everything toward the center of the Earth

The gravitational attraction between two objects would increase if both masses are –

• increased, and the distance between them is increased.

• increased, and the distance between them is decreased.

• decreased, and the distance between them is decreased.

• decreased, and the distance between them is increased.

Why do planets orbit the Sun?

• The Sun is the only celestial object that has a gravitational pull.

• The Sun’s chemical composition makes it attract planets.

• Only celestial bodies that emit light, like the Sun, can be at the center of an orbit.

• The Sun is the most massive object in our solar system, so it exerts the greatest gravitational pull.

• increases.

• decreases.

• stays the same.

• has no effect.
